However, a direct link between FGF signaling and crystallin gene transcriptional machinery remains to be established. Previously, we have shown […]

Structural and mechanistic insights into the regulation of the fundamental Rho-regulator RhoGDI{alpha} by lysine acetylation Protein Structure and Folding

Rho-proteins are small GTP/GDP-binding proteins primarily involved in cytoskeleton regulation. Their GTP/GDP-cycle is often tightly connected to a membrane/cytosol-cycle regulated by the Rho guanine nucleotide dissociation inhibitor α (RhoGDIα). RhoGDIα has been regarded as a housekeeping regulator essential to control homeostasis of Rho-proteins. Recent proteomic screens showed that RhoGDIα is extensively lysine acetylated. Here, we […]

Distinct Developmental Functions of Prostasin (CAP1/PRSS8) Zymogen and Activated Prostasin Enzymology

The membrane-anchored serine prostasin (CAP1/PRSS8) is essential for barrier acquisition of the interfollicular epidermis and for normal hair follicle development. Consequently, prostasin null mice die shortly after birth. Prostasin is found in two forms in the epidermis: a one-chain zymogen and a two-chain proteolytically active form, generated by matriptase-dependent activation site cleavage. Here we used […]

orlsfakianakisστοOtoRhinoLaryngology by Sfakianakis G.AlexandrosΠριν από 1 ώρα
Hypersensitivity Pneumonitis is an interstitial lung disease that develops following repeated exposure to inhaled environmental antigens. The disease results in alveolitis, granuloma formation and progresses to a chronic form associated with fibrosis; a greater understanding of the immunopathogenic mechanisms leading to chronic HP is needed. We used the Saccharopolyspora rectivirgula (SR) mouse model of HP… Continue reading Chronic hypersensitivity pneumonitis caused by Saccharopolyspora rectivirgula is not associated with a switch to a Th2 response.

Molecular Pathways: Mechanism of Action for Talimogene Laherparepvec, a New Oncolytic Virus Immunotherapy

Oncolytic viruses are native or engineered viruses that preferentially replicate in and lyse cancer cells. Selective tumor cell replication is thought to depend on infection of neoplastic cells, which harbor low levels of protein kinase R (PKR) and dysfunctional type 1 interferon signaling elements. These changes allow more efficient viral replication, and with selected deletion […]
